  • 🔒 Security type: some older adapters (eg in Inspiron 15 3000 2015) do not support WPA3Switch the router to WPA2-PSK (AES).
  • 📶 Channel and channel width: if the router is operating on the channel 13–14 (not allowed in all countries) or width 80 MHz, try installing the channel 6 and width 20/40 MHz.

To change router settings:

  1. Connect to it via cable (or from another device where Wi-Fi works).
  2. Open your browser and enter the router's address (usually 192.168.0.1 or 192.168.1.1).
  3. Log in (default logins: admin/admin or admin/password).
  4. Find the section Wireless Settings (or "Wireless network") and make changes.
⚠️ Attention: If after changing the router settings Wi-Fi stops working on all devices, reset it to factory settings (button Reset on the back panel).
